Wuidail Cold Air Intake — F22/F30/F32 N55 3.0L (335i/435i/M235i)

On the road, the difference is immediate. Throttle response sharpens noticeably, and the broader torque curve makes the N55 feel more alive through the midrange — exactly where you live during spirited driving or highway on-ramp pulls. Wuidail rates this kit at up to 10 hp and 22 lb-ft of torque, figures that align with what a well-engineered intake can realistically unlock from a force-fed inline-six.

Fitment covers three distinct chassis: the F30 335i sedan (2012–2018), the F32 435i coupe (2014–2018), and the F22 M235i coupe (2014–2018). Every unit is tested before leaving the factory, and installation is designed to be straightforward without permanent modification to the engine bay. That said, Wuidail recommends professional installation to ensure everything is sealed correctly and torqued to spec.

One critical note before you add to cart: this kit is engineered exclusively for the N55 3.0T inline-six. It is not compatible with the N20 2.0L four-cylinder found in some same-year 328i and 428i models. Double-check your engine code before purchasing to guarantee a clean, correct fit.
